You can hike with th ULF cameras. I can't remember where, but a few years ago i read an article about someone hiking with an 11x14 camera. He basically modified an old backpack rack to hold camera, film and tripod. I beleive he had a tripod modified so he could break it down into the seperate head and legs in able to better balance the load. I myself have a problem knee, injured and operated on a couple of different times and it can be difficult for me to backpack a load of that size.
